SLEIGH RUNNING-GEAR.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed November 24, 1906. Serial No. 344,935.

To all whom it may concern:

Be it known that I, EDGAR PERRY, a citizen of the United States, residing at Caribou, in the county of Aroostook and State of Maine, have invented a new and useful Sleigh Running-Gear, of which the following is a specification.

This invention has relation to running gears for sleighs and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to provide a running gear composed of runners, raves and knees connecting the same together. The knees are so arranged as to increase the strength of the running gear without adding materially to the weight thereof and by their arrangement they brace each other and also positively hold the raves in fixed relation to the runners. The said knees are arranged in pairs and the members of each pair are comparatively in close proximity to each other. However, upon each runner the distance between the members of one pair is different from the distance between the members of every other pair. This peculiar relative spacing of the pairs and the members thereof has the desired effect of bracing the running gear without adding materially to the weight thereof.

In the accompanying drawing:the figure is a perspective view of a sleigh showing the running gear.

The running gear comprises the runners 1, 1 to the forward ends of which are attached the forward ends of the raves 2, 2. The said raves are connected together by the usual cross bars 3, 3. The knees 4 are interposed between the runners 1 and raves 2. As shown in the accompanying drawing, the said knees 4 are arranged in three sets of pairs 5, 6 and 7. The members of each pair are comparatively in close proximity to each other, that is to say, the space between the pairs is greater than the space between the members of the pairs. Also, the space between the members 4, 4 of the pair 7 is greater than the space between the members 4, '4 of the pair 5 and the space between the members 4, 4 of the pair 5 is greater than the space between the members 4, 4 of the pair 6. The pair 7 is located at the forward portion of the running gear while the pair 6 is located at the intermediate portion thereof and the pair 5 at the rear portion thereof. The cross bars 3, 3 join with the raves 2, 2 at points between the members of the pairs 5, (3 and 7. Braces such as 8 may be provided between the runners 1 and raves 2 and braces such as 9 may be provided between the knees 4 and the cross bars 3.

From the foregoing description it is obvious that the irregularity of spacing of the pairs of knees and the irregularity of space between the members of each pair of knees will prevent vibration of the same degree of the parts located between the knees. Consequently, the different portions of the runners and raves being compelled to vibrate at different degrees unanimity of vibration is destroyed and racking of the structure consequent to such vibration is avoided. It will be observed that the space between the pairs of knees 6 and 7 is greater than the space between the pairs of knees 5 and 6. The knees 5 and 6 are located substantially under that portion of the vehicle body which is to sustain the'greatest weight, hence such knees should be closer together and as the greatest weight occurs substantially over the knees 4 of the pairs 6 the last said knees are placed closer together than the knees of the other pairs.

Having described my invention what 1 claim as new and desire to secure by Letters-Patent is:

1. A sleigh running gear comprising runners. raves attachcd thereto, knees located between the rates and runncrs, said knees being arranged in pairs, the space between the members of the pairs being less than the space between the pairs and the space between the members of one pair differing" in length from the space between the members of the other pairs.

2. A sleigh running gear comprising runners, raves attached thereto, knees located between the raves and runners, said knees being arranged in pairs, the space between the members of the pairs beingless than the space between the pairs and the space between the pairs differing in dimensions.

3. A sleigh running gear comprising runners raves attached thereto, knees located between the raves and runners and being arranged in pairs, the space between the members of the'pairs being less than the space between the pairs, the space between the forward pair of knees be ing greater than the space between the members of the rear pair of knees and the space between the members of the rear pair of knees being greater than the space between the intermediate pair of knees.

4. A running gear for sleighs comprising runners, raves attached thereto, knees located between said raves and being arranged in pairs, the space between the members of the pairs being less than the space between the pairs, the space between the members of the forward pair being greater than the space between the members of the rear pair and the space between the members of the rear pair being greater than the space between the members of the intermediate pair and the space between the forward and intermediate pair being greater than the space between the intermediate pair and the rear pair.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of'two witnesses.

EDGAR PERRY.
